Title: Light-emitting diode display devices
IPC: G09F9/33
Filed: 1974-12-12
Abstract: 1495398 Alpha-numeric displays TEXAS INSTRUMENTS Ltd 12 Dec 1974 53748/74 Heading G5C A monolithic display device comprises a plurality of electroluminescent numeral displays each consisting of a pattern of semi-conductor bars of a first conductivity type 6A-G and decimal dot 7 embedded in a semi-conductor island of the opposite type, a semi-conductor plate 1 of the first type supporting the islands, each pattern of bars forming mineral, electrical conductors which lie on the surface of the device and connect corresponding bars of each device to terminal pads 9-15, and second terminal pads connected to respective ones of the semiconductor islands. The islands may be separated by s/c material 8 of the first type (cf, also Fig.3, not shown), or by air or other dielectric. The s/c plate may be square or rectangular the islands being in linear array in the latter case and a lens system not being required. An optical system (e.g. with a single unit moulded polystyrene multi lens system (28) (Fig. 6, not shown) may provide an enlarged image on a screen. The lens pairs are offset to produce the side by side image, and dimensions of the system prevent multiple images. In Fig. 4, pads 9-16 are isolated from the base by a dielectric layer, the base may be GaP transparent to the LED emissions, or GaAs transparent to red only. An epitaxial layer of GaAsP or GaAlAs may be formed covered by a mask of silicon oxide or nitride mask, while GaP requires silicon dioxide between nitride, and channel 8 formed by diffusion through the etched mask. A conductive layer (e.g. of Al) is then deposited and etched to provide conductors and pads. Control may be via clock pulse generator (22), shift register (20), decoder (21) and keyborad (23) (Fig. 5, not shown). Register and decoder may be on a common chip, and with the display and clock pulse generator could be mounted on a thick film substrate or printed circuit board. Part of the clock pulse generator may be on the register-decoder chip. Pocket size calculator applications are exemplified.

Filed: 1971-11-23
Abstract: 1413792 Measuring web tension MASSON SCOTT THRISSELL ENG Ltd 21 Nov 1972 [23 Nov 1971] 54242/71 Heading G1A [Also in Divisions G3 and H4] The tension in a stretched web is measured by exciting the web to produce transverse vibrations thereof and sensing vibratory movements of the web at two positions there along to produce two signals, the time difference between which is used to obtain a measure of the web tension. In the arrangement of Fig.1, the web is excited into vibration by a pulsed loud-speaker, mechanical or electrostatic means or an air jet, Fig.4 (not shown). The vibrational disturbance in the web is sensed at two locations to determine the time for it to travel a predetermined distance. The propogation velocity is indicative of web tension. An indicator (voltmeter) or servo-control for braking are coupled to the output of the time measuring device. In alternative arrangements, transducers other than photo-electric devices sense the vibrations of the web e.g. microphones.

Title: Improvements in and relating to the Manufacture of Liquid-Filled Sweets
IPC: A23G1/18
Filed: 1967-12-01
Abstract: 1,172,417. Liquid-filled sweets. ASBACH & CO. 1 Dec., 1967 [3 Dec., 1966; 30 May, 1967; 1 Aug., 1967; 14 Oct., 1967], No. 54718/67. Headings A2A and A2B. In a method and apparatus, Fig. 1, for manufacturing liquid-filled sweets, e.g. liqueur-filled chocolates such as brandy beans, each having a core comprising an aqueous, flavoured, saturated solution of sugar enclosed in a crust of sugar which has been deposited from said solution, a hot aqueous solution of sugar, e.g. having a temperature of 110‹C., is prepared in a tank 55 and passed into a tank 54, in which a desired flavouring e.g. one or more than one alcoholic distillate such as brandy, is mixed with the solution, which then flows into a supply tank 1, and thence flows downwardly, in the form of a film or spray, through an outlet slot 11 controlled by a slidable gate 12, over the cooling pipes 13 of a cooler 2, so that the solution is rapidly, e.g. suddenly, supercooled to a temperature below the saturation temperature for sugar in the solution, e.g. to 35‹C., or below, preferably between 26 and 28‹C. The supercooled, supersaturated solution passes, through a trough 3 and a tank 4, into a pouring tank 5. A temperature gauge may be provided in the tank 5, the tank 4 or the trough 3, and' connected to a device actuating the gate 12, so that the gate 12 is moved to narrow the slot 11 when the temperature of the solution rises, or to widen the slot when the temperature falls. An intermittently moving conveyer 7 brings an empty mould 8 having a plurality of cavities, e.g. formed in an edible powder, under a corresponding plurality of outlets 30 in the base of the tank 5. The conveyer is then halted, and the outlets 30 are opened, e.g. by electromagnetically raising plates covering them, so that the supercooled, supersaturated sugar solution is dispensed into the cavities. When these are filled with solution, the outlets 30 are closed, e.g. by electromagnetically lowering said plates to cover the outlets, and the conveyer 7 is then re-started to move the filled mould 8 away from the outlets and bring another empty mould under them. Sugar crystals are not deposited from the supercooled, supersaturated solution of sugar until it has been dispersed into the cavities. The resulting crust-enclosed, moulded cores are then removed from the filled mould 8 and, if desired, coated with chocolate. Alternatively, the supercooled, supersaturated sugar solution may be dispersed into previously moulded hollow chocolate bodies, which may then be closed in a conventional manner. Means, including a gauge which senses the level of the sugar solution in the tank 5, and a switching element which controls the inflow of the sugar solution, may be provided to maintain said level substantially constant. The whole of the apparatus may be electrically controlled to function automatically.

Title: Improvements in or relating to pneumatically operated percussion driving tools
IPC: B25C1/04
Filed: 1965-12-24
Abstract: 1,080,657. Nailing and stapling. JOH. FRIEDRICH BEHRENS. Dec. 24, 1965 [Dec. 28, 1964], No. 54818/65. Heading B4C. A pneumatically-operated percussion tool for driving fasteners, such as nails or staples 15, comprises a driving piston 80, reciprocable in a cylinder 30 which is displaceably mounted in a casing 20, inlet openings 37 being provided in the cylinder wall for pressurized air under the control of a piston valve 40 mechanically coupled to the cylinder. The cylinder 30 is formed with a flange 43 slidable in a chamber 44 and provided with a seal 45 adapted to contact the upper edge of the casing part in which the cylinder moves. A control piston insert 41 is movable within the flange 43 and is formed with an extension 42 arranged to abut a seal 55 in a head portion 11 of the easing. In operation, with the tool in the position shown, air is fed from a reservoir 13 through a port 116, passages 105, 109 into the chamber 44 to thereby maintain the flanges 43 and insert 41 in the closed position, air above the piston escaping through a bore 49 in the insert and ports 52 in the head 11. Upon actuating a valve 123, 124, the flow of air to the chamber 44 is prevented, thereby allowing air in a chamber 23 to raise the flange and insert so as to permit the piston to be driven downwardly on its working stroke. During this stroke, air in front of the piston is exhausted via an annular passage 65 and ports 28 in the casing; air is also forced through ports 36 in the cylinder, into a chamber 25. Towards the end of the stroke, the piston strikes a resilient member 60 sealingly held in the cylinder and thereby moves the latter downwardly so that the bottom end of the cylinder closes the outlet ports 28. When a trigger 125 is released the valve 123, 124 is opened and the piston returned by the air compressed in the chamber 25. In order to prevent the tool from being used until it is pressed against a workpiece, a feeler 135 is connected to rod 100 via a lever 132 such that when the tool contacts a workpiece the rod is moved into a position in which a pin 128 on the trigger can enter a recess 104 in the rod. A magnet 47 is mounted on the valve insert 41 in order to retain the piston in its raised position.

Abstract: 1386369 Tamperproof closures V WASSILIEFF 5 Dec 1972 [6 Dec 1971] 56099/72 Heading B8T A tamperproof container closure has an element A with an internal annular projection 5 which forms a skirt for sealing with a container neck. An element B is axially movable so that when it is pressed down the bevelled face 12 slides over the annular projection 4 thus compressing the sealing lip 5. At the same time the washer 17 which is integrally moulded with the top 10 rides over a central peg 6 so that the flange 7 engages on the top of edge 23 thus imprisoning the washer 17 under the flange 7, Fig. 3 (not shown). To open the container element R is pulsed upwards thus freeing the projection 4 for unsealing the container top and at the same time the washer 17 breaks along the rupture points (20), Fig. 2 (not shown), and falls on the top 1, Fig. 4 (not shown). When the element B is lowered to reseal the container, a difference in level exists between the top 10 and the washer 17, Fig. 5 (not shown), thus indicating that unsealing has taken place. In a modified version the washer 17 is replaced by a solid plug disc (30), Fig. 6 (not shown), co-operating with a recess (33). In a further version, Figs. 8 and 9 (not shown), the element B and washer 17 correspond generally to the construction shown in Fig. 1, but to open the container the element B engages under the washer 17 which then abuts the peg to pull off the closure element A. After replacement of the closure a similar indication of previous access is given by the level of the washer 17.
